Usually when alternators go bad the Antilock is not functioning either. I have seen it happen. My friend has a Pontiac Sunfire, well we were driving around and the ABS light came on, he told me to check the owners manual and it said to turn the car off and turn it back on to reset the ABS. Well he pulled into a parking lot, turned the car off and tried to start it again, well there was a click. His alternator went bad but his charging light never came on. For some reason charging lights never seem to come on in cars, my fathers old cadillac deville had a bad alternator yet no charging light, my mothers corsica had a bad alternator yet no charging light. Maybe just american cars, havent been able to experience it on my MB. Anyhow back on topic, I would guess you need a new OVP.
